Sahithyan's S1 — Properties of Materials

Ductility

A measure of the degree of plastic deformation at fracture.

Most metals are ductile. Ductile materials have high tensile strength.

Percentage elongation

Section titled “Percentage elongation”
lf−l0l0×100\frac{l_f - l_0}{l_0} \times 100%

Percentage reduction in area

Section titled “Percentage reduction in area”
A0−AfA0×100\frac{A_0 - A_f}{A_0} \times 100%

Brittle

Section titled “Brittle”

A material that experiences very little or no plastic deformation.

Brittleness order: Ionic bonds > Covalent bonds > Metallic bonds

Malleability

Section titled “Malleability”

Ability of a material to undergo plastic deformation under compression.

Ductility & Brittleness

Section titled “Ductility & Brittleness”

Depends on:

  • Composition of the material
  • Temperature
